The fourth snatch of song Mr. Halloway comes up with is now best known as the second part of the folk song “I’ve Been Working on the Railroad,” which turned up in a collection of Princeton University songs in 1894. The Dinah portion comes from “Old Joe, or Somebody in the House with Dinah,” which was published in London in the 1830s or 1840s. Dinah was a generic name for an African slave woman.
